How is the steel steerer fixed into the aluminium crown? Would it not have been possible to remove the existing steerer and replace with a longer one?

@paulbrodie

No, I only have a Campy set.

I've done this before without machine tools: Not all 1" threaded fork tubes are the same! Check your headset on the donor fork to make sure it fits well. For a 1" threaded fork, you can use a 22.2mm seat post as the pipe that attaches donor to original fork. These are common on old schwinns and new cheap kids bikes. You don't have to butt the end of the donor fork to the end of the old fork. You can leave the pipe exposed in the middle. If you don't do this, you will have a hard time finding a long enough donor fork. Leaving some pipe showing in the middle allows you to use a fork from a 56-58cm bike and have a decent amount of quill stem adjustment. The fork I extended was for a 64cm bike. Will this make it weaker and allow it to flex and bind the headset? IDK I didn't notice any difference. You don't have to clean the welds. I stick welded mine and left the welds lumpy inside the head tube. They don't rub and they can't be seen, so I didn't care to grind them down.

Is it possible to extend the steel steerer of a carbon fork? Also, is it possible to cut more threads on a steel steerer?

What was the thickness of the chromoly extension tube you used? I only saw you mention 0.083" for the insert. Do you have any advice about extending a steerer tube for a tallbike? It would be nice to use a thin steerer tube (0.035") to keep the weight down (not much stress at the very top), but not sure how thick it needs to be at the top of the existing fork steerer.

@paulbrodie

Жыл бұрын

Yes, the insert is .083" wall thickness. To extend the "steerer tube" I used another steerer tube. The wall thickness is 1.5mm, or approx. .060". These are all industry standards. A steerer tube of .035" would be grossly inadequate. Don't use it.

It's possible, but I would not recommend it. A steerer tube will flex over rough terrain, and braze tends to crack from flexing. That's why Tig welding is better; it resists cracking from flexing.

Paul, there is a study "Strength of Thin-Walled, Butt-Welded Steel Tube" by Cameron Daugherty and Dr. Mark Archibald at Grove City College" (sorry, can't post the link).

I there a risk in making the steer tube much stiffer than normal? I’ve heard a lot of the flex in the fork can occur in the steer tube. The crown on the Brodie fork is really beefy, so maybe it doesn’t matter on his fork, but on a cheap fork I could see it being an issue. I suppose it depends on how the bike will be used/ridden.
